Gamma-ray resistant modified PC muaj kev nyab xeeb dua nyob rau hauv kev kho mob thiab xav tau daim ntawv thov, tshwj xeeb tshaj yog thaum hluav taws xob sterilization, tib neeg kev sib cuag, los yog ntev - lub sij hawm stability yuav tsum tau; nws txoj kev nyab xeeb yog qhov zoo tshaj rau PC li niaj zaus.
1. Core Safety Comparison
|
Kev nyab xeeb Dimension |
Ordinary PC |
Gamma{0}}Ray Modified PC |
|
Biocompatibility |
Feem ntau ua tsis tau biosafety xeem xws li ISO 10993, tej zaum yuav muaj additives tsim teeb meem rau tib neeg |
Kev soj ntsuam nruj thiab tau lees paub, ua tau raws li ISO 10993 thiab USP Class VI cov qauv, tsim nyog rau cov khoom siv kho mob |
|
Irradiation Stability |
Yooj yim yellows, ua nkig, thiab tawg tom qab gamma irradiation, tej zaum yuav tso tawm hais los yog teeb meem tshuaj. |
Tshwj xeeb tsim los tiv thaiv 25-50 kGy irradiation, tswj cov qauv kev ncaj ncees, thiab tsis tsim cov khoom tsim kev puas tsuaj |
|
Kev nyab xeeb tshuaj |
Tej zaum yuav tso cov endocrine cuam tshuam xws li bisphenol A, tshwj xeeb tshaj yog thaum kub kub los yog nyob rau hauv irradiation; Kev hloov kho cov txheej txheem txo qhov kev pheej hmoo ntawm kev tso tawm cov tshuaj phem, ua kom muaj kev nyab xeeb dua rau kev sib cuag nrog cov tshuaj thiab cov kua dej hauv lub cev. |

|
Kev Siv Scenario Kev Nyab Xeeb |
Haum rau cov khoom tsis yog- tsis muaj menyuam, tsis yog-ntev- lub sijhawm tiv tauj cov khoom lag luam, xws li cov khoom siv hluav taws xob |
Tshwj xeeb tsim los rau siab - xwm txheej kev nyab xeeb xws li cov cuab yeej siv kho mob pov tseg thiab cov khoom siv cog tau |
Cov ntsiab lus tseem ceeb: Rau cov ntawv thov hauv cov khoom siv kho mob, ntim tshuaj, lossis cov xwm txheej xav tau gamma sterilization, PC zoo tib yam ua rau muaj kev nyab xeeb tseem ceeb, thaum gamma - hloov kho PC yog qhov kev xaiv ua raws thiab txhim khu kev qha.
2. Kev txiav txim siab txog kev nyab xeeb hauv Wuhan qhov kub thiab av noo ib puag ncig: Hauv Wuhan, huab cua kub thiab av noo ua rau cov khoom laus zuj zus. Ordinary PC feem ntau ua rau hydrolysis thiab oxidation tom qab irradiation nyob rau hauv ib puag ncig ntub, ua rau muaj kev poob qis hauv kev ua haujlwm; thaum gamma- tiv taus hloov kho PC feem ntau muaj zog tiv thaiv kom ntub dej kub thiab av noo, thiab nws cov qauv kaw tau zoo tiv thaiv microbial intrusion thiab khoom degradation.
3. Yuav ua li cas kom muaj kev ruaj ntseg ntawm cov khoom?
Cov ntaub ntawv pov thawj: Ua ntej cov khoom lag luam uas muab ISO 10993, ISO 11137, thiab FDA cov lus tshaj tawm ua raws.
Thov daim ntawv pov thawj ntawm tus account (COA) Daim Ntawv Qhia: Tshuaj xyuas cov ntaub ntawv ntawm cov khoom siv kho tshuab, kev xa tawm, xim txawv, thiab lwm yam, ua ntej thiab tom qab irradiation los xyuas qhov tseeb stability.
Zam Kev Txiav Txim Raws Li Kev Pom Zoo nkaus xwb: Qee lub PC zoo ib yam yuav tsis muaj kev hloov pauv hauv lub sijhawm luv luv, tab sis yuav maj mam txo qis dua - siv sijhawm ntev, ua rau muaj kev pheej hmoo zais.
